Patented Dec. 8, 1931 UNITED STATES PATENT oFFlcE i DATIF S. JACOBUS, OF MONTCLAIR, NEW ERSEY, ASSIGNOR TO FULLER LEHIG'H COM- PANY, 0F FULLERTON, PENNSYLVANIA, A CORPORATION OF DELAWARE SEUJJIONAL FURNACE WALL Original application led January 13,

This application is a division of kmy copending application Serial No. 2,081, filed January 13, 1925. The invention will be best 'understood from the following description.

same plane as Fig. 1, and showing a fragment of the wall.

Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a section on the line 4-4 of Fig. 2. Figs. 5, 6 and 8 are views corresponding to Fig. 3, but showing other forms which the invention may take.

Fig. 7 is a section on the line 7 7 of Fig. 6.

I have shown the invention as applied to a furnace having a combustion chamber 1 located beneath a boiler 2 of the horizontal tube construction, the details of which will not be described. A suitable gasoutlet 3 is provided for the gases which have passed over the boiler, and the gases pass from this flue through an air heater 4 to the outlet 5. A fan 6 is provided to force air throughthe heater 4 to an air inlet 7 which connects with ducts 8 formed in the rear furnace wall. The details of these ducts will be 4more fully described later.

The air from the ducts may be discharged through apertures 9 into the space beneath the floor 10 of the furnace. The air may then rise through ducts in the side walls, which are similar tothe ducts 8, into a duct 11 adjacent the top of the furnace, one of these ducts being arranged on each side of the furnace and then the air may be discharged into the ducts 8 in the front wall of the furnace. These ducts may be connected to the combustion chamber by apertures 12 so that the air may enter the chamber from 'the front wall. If desired, some of theair which has been thus heated may be supplied to the burner 13 which is here shown as a pulverized fuel burner.

l Preferably, I construct the walls of the fur- 1925, Serial No. 2,081'. Divided and this application led December '4, 1928. Serial No. 323,717.

nace so that they are, in effect, made up of independent sections which sections may be made as small as desired. I also preferably construct these sections so that the parts of any one of them may be taken out and-replaced without disturbance of the remainder of the-wal1, and I also arrange these sections in relation to each other so that relative movement may take placetherebetween so as to take up the expansions and contractions to which such a wall is subjected.

I have shown the furnace wall as com rising a plurality of vertically arranged ed vsupports 14 which may be in the form of the usual I-beam section. Connected to the supports 14, I have shown short channel sections 15 connected at their inner iianges to horizontally extending bars 16.l Supported on each of the bars 16 is a plurality of separate supports 17, each provided at its upper end with a hook '18 adapted to hook over a bar 16. The lower end of each support 17 rests upon the next lower. bar 16.

Each support is providedadjacent its inner edge, by which I mean the edge nearest.

the furnace, with a projection`or bulb 19 adapted to be received in recesses 20 in tile 21. In the form shown, these recesses are formed in the adjacent faces of the two tile,

as best seen in Fig. 3, and these adjacent faces are provided with offset portions 22 whereby radiant heat from the furnace will not be permitted to strike the supports. Placed rearwardly from'the backs 23 of the tile 21, are projections 24 on the supports, and in the form shown in Figs. 2 and 3, I have indicated an insulating material 25 held in-place against the backs of the tile by the projections; The lower part of each support has an inwardly projecting portion 26 which is received in a recess of the lowest tile carried by the support, and a suitable expansion joint is formed by introducing a suitable material 27 between this lowest tile and the top tile on the y next support below. A suitable casing 28 is supported at a distance from the tile, and supports 17, so as to form space for the circulation of air in the manner described above.

In Fig. 5, I have shown a different form of the invention, and in which the tile 21 are 'supported on bulbs 29 of supports 30. In

this form, the projections on the supports disposed rearwardly from the wall are in the form of bulbs 31 on the opposite edges of these supports. Between the supports are plates\32 which are preferably sprung into place so as to have --their edges Contact with the projections or bulbs 31. These plates may conveniently be formed so as to seal the space between thesupports 30. Each of the'plates 32 has a threaded hole to receive a bolt 33 which is provided at its inner end with a large head 34 bearing against a plate` 35 resting against the back of the tile 21. By this arrangement, the plates'35 may be held tightly in position, and consequently the tile may be also held in position. The edges of the plates 35 are turned up, as shown at 36, so that if it is desired, a suitable plastic backing, not shown, may be inserted beneath'k them.

In Figs. 6 and 7, I have shown the Wall as I formed of two kinds of tile, the wall tile 37 being carried on the bulbed supports 38 which are provided with projections 39 between which and the backs of the tile the insulating material 40 may be placed. In this form, IV

have shown the insulating material, which of course is normally a plastic material, as reinforced by means of metallic members 41 of any suitable form. These members may conveniently be arched` and sprung into place between the projections 39 on adjacent supports 38. Preferably, each of the tile 37 has recesses 42 in the inner face thereof adapted to receive corresponding projections on facing tile 43. l In the form shown, these recesses are in the shape of grooves at the top of the tile and extending horizontally on the wall, and the corresponding projections on the facing tile are in the form of hooks adapted to be received in the grooves. The bottom of eachlof thektile 37 is provided adjacent its bottom with a recess 44 so that the hook on the facing tile next lower 'can be raised and removed through the groove in the wall tile.

In Fig. 8, I have shown a form which cor-` A responds in. all principal particulars to the form shown in Fig. 6, and to which corresponding numeralsy have been applied. In this form thew'facing tile, however,- are omitted. the wall tile 37 being modified accordingly' to omit the grooves for the support of the facing tile.

In operation, the air is discharged into thejspace between the tile, and the casing in the rear' thereof, this., space being substantially divided into ducts' by means of the channels 15 and the supports 1'?, 30 or 38', as the casemay be. lhe walls-or the ducts are o course not continuous, but nevertheless they serve to direct the dow of air and, at the sametime, permit relfnsively free circulation been described above and will not be report having a vertically disposed bulbed p rib thereon, and tile having recesses to engage said bulbed rib, each tile support having aprojection beneath the row of tilecon? nected to said rib to support said row, each tile support having a vertically disposed projection on its outeredge and filling material between each pair of tile supports and held in place by said vertically disposed projections to form 'with said supports a substantially continuous backing plate for said wall.
